AI Technical Summary

Problems solved by technology

The greater the number of subsystems, the longer this delay makes it difficult to integrate new subsystems on existing platforms
Also, the length of the delay must be known before sending the first instruction to the subsystem

Embodiment Construction

[0029] figure 1 is a schematic diagram of a motor vehicle showing, in block form, some of the components relevant to the present invention. It should be understood that these components are not necessarily essential to the invention, and that the invention is applicable to other illustrated components as well.

[0030] The steering wheel 1 controls the steering angle of the front wheels 2 of the motor vehicle using a power steering controller 3 . The power steering controller 3 has an actuator for turning the front wheels 2 in proportion to the angular position of the steering wheel 1 and an actuator for exerting on the steering wheel 1 a counter torque to the torque applied by the driver. The power steering controller 3 supports several operating states which differ from each other according to the degree of assistance provided to the driver, i.e. according to the ratio between the force required to turn the front wheels 2 and the reactive torque experienced by the driver r...

Abstract

A method for jointly controlling a plurality n, n being an integer greater than 1, of devices (3, 6, 7, 10) connected to a same communication channel (12), each of said devices D1 (3, 6, 7, 10), 1 = 1,..., n, being capable of assuming a number m1 of states, comprises the steps of a) unambiguously assigning to each combination of states of said n devices an integer code number M, wherein M e [x, x+*m1, [, x being an arbitrary number, b] for a combination of states to be set in the devices, selecting the code number M assigned to said combination (m5), c] broadcasting (m2) said code number M toall devices Di1 (3, 6, 7, 10), 1 = 1,..., n via said communication channel (12); d] decoding (s2), in each device (3, 6, 7, 10), the state to be set in that device from said code number M; e] setting(s3) the decoded state in each device (3, 6, 7, 10).

Description

technical field [0001] The present invention relates to methods and apparatus for jointly controlling a plurality of devices, and more particularly, to methods and apparatus for controlling individual subsystems in a motor vehicle. Background technique [0002] In recent years, a large number of control subsystems of motor vehicles have been developed to assist the driver in different aspects. One known type of control subsystem is automatic braking control, which detects changes between the rotational speeds of the wheels of a motor vehicle and controls the braking force applied to the wheels in order to prevent the wheels from slipping. Another prior art control subsystem is known as ESP (Electronic Stability Program), which detects the steering wheel angle corresponding to the driver's desired track curvature, compares it to the actual track curvature, and in case of a substantial difference , to brake certain wheels in order to allow the vehicle to travel along the desi...
